Things may have changed since 2013 but back then, we checked in for outward and inbound long haul flights as normal. For most of the internal flights, check in was done for us. Our luggage was collected from the rooms, and taken ahead to check in. When we arrived at the airport, our tour manager was handed all the baggage receipts, and boarding passes. The system worked really well, and minimised the time we spent in the airports.
